Separation of iron particles from coolant fluids (case study)
Initial status
We were approached by a significant Czech engineering company specialized in pressing, machining and production of automotive shafts, dampers, nozzles, differentials, pressure filters etc. They have renowned clients such as BMW, Daimler, Volkswagen, Porsche, as well as non-automotive companies like HILTI, BOSCH and others.
Problem
The customer uses the metalworking fluid (Hysol) to cool the vertical turning center EMAG VL3DUO. Afterwards, large ferromagnetic chips are removed from the cooling fluid by a magnetic conveyor (which is directly immersed in the cooling bath). However, small ferrous contaminants (coming from the machining process) cannot be captured by this type of separator, and as a result, they used to recirculate back into the EMAG machining center. The high concentration of these particles in the coolant led to repeated equipment damage and costly production downtimes.
Solution
Due to the poor magnetic separation results of the magnetic conveyor, the customer decided to borrow a trial unit of our magnetic trap MSP-MC 50 N (and we modified the appliance so that the client could connect it to his DN 28 flanges). Afterwards, the customer kept testing its magnetic efficiency directly on his cooling circuit for a period of 14 days.
Benefits of our solution for the client
The test results exceeded the customer's expectations. Our pipeline magnetic filter MSP-MC 50N reliably separated even extremely small ferromagnetic particles (starting from a size of a few microns). The customer was so satisfied with its performance that they decided to purchase the borrowed device immediately. The magnetic trap MSP-MC not only eliminated unwanted downtime but also contributed to improved surface quality of the machined parts and significantly extended the life of the expensive coolant.
